Why is it 1/30th of the pot though, that's not a block bet, that's barely even a bet? And what are you trying to block a bet from? The only thing he can have on this board is a full house, a flush or a straight, a weaker pair than you or a busted spade draw. With the weaker pair, this bet gets no value, but with everything else you are getting raised/shoved including possibly busted spades but since there's so many hands villain could have its tough to call.

Four callers is really unlucky, if people are calling preflop raises that light, a raise of 0.12 with AA means you give them incorrect odds to set mine you (not that they'll be noticing this, but it'll mean more money in the pot for you when they don't hit).

I see where you're coming from though in calling, in NL2 its hard to let go of aces because of the crazy bluffs people will run with absolute air
